While looking for an accessible, turn-based strategy game, I stumbled upon Tiny Token Empires. Brilliant game, mixing turn-based strategy with a "Match 3" puzzle game. This mix of puzzle game with another type of game already worked quite well in Puzzle Pirates, Puzzle Quest, and Might & Magic Clash of Heroes. And Tiny Token Empires shows that it works equally well for turn-based strategy games as it works for role-playing games.

I picked the game up for €9.95 in a shop. You can download a demo of the PC version on their website, but you'll find no info there on the digital distribution. I've seen the PC digital download version for $19.95 on Amazon.com and much cheaper at Wild Tangent Games, but I don't really like Wild Tangent's business model where you have to buy WildCoins first. The game is available on Mac, iPhone, and iPad via the Apple app store; but the iPhone version appears to sell you a basic version of the game for cheap, and then sells you the campaigns extra.
